ALSA: fireworks: fix wrong return count shorter than expected by 4 bytes
commit eb9d84b0ffe39893cb23b0b6712bbe3637fa25fa upstream. ALSA fireworks driver has a bug in its initial state to return count shorter than expected by 4 bytes to userspace applications when handling response frame for Echo Audio Fireworks transaction. It's due to missing addition of the size for the type of event in ALSA firewire stack.
